Palmitoleic acid, an ω-7 monounsaturated fatty acid found in macadamia and sea buckthorn oils, enhances both basal and insulin-stimulated glucose uptake, as well as Glut4 protein levels in 3T3-L1 adipocytes at a 200 µM concentration. Ex vivo, at a dosage of 300 mg/kg per day, it significantly increases glucose uptake and both aerobic and anaerobic glycolysis, while decreasing de novo fatty acid synthesis and the activity of lipogenic enzymes, specifically ATP citrate lyase (ACL) and glucose-6-phosphate dehydrogenase (G6PDH), in isolated murine adipocytes. Furthermore, the dietary administration of palmitoleic acid at 300 mg/kg mitigates high-fat diet-induced insulin resistance and liver inflammation in mice.
9(Z),11(E)-Conjugated linoleic acid is an isomer of linoleic acid that has been found in beef and milk fat.1It binds to peroxisome proliferator-activated receptor α (PPARα; IC50= 140 nM) and activates the receptor in a reporter assay using COS-1 cells expressing mouse PPARα when used at a concentration of 100 μM.29(Z),11(E)-Conjugated linoleic acid inhibits TNF-α-inducedGLUT4expression and increases insulin-stimulated glucose transport in 3T3-L1 adipocytes.3Dietary administration of 9(Z)11(E)-conjugated linoleic acid reduces serum fasting glucose, insulin, and triglyceride levels and decreases white adipose tissue macrophage infiltration inob/obmice. It also increases body weight gain and body fat in weanling mice.4[Matreya, LLC. Catalog No. 1278]

1-Oleoyl-2-hydroxy-sn-glycero-3-PG (sodium salt), a lysophospholipid with oleic acid (18:1) at the sn-1 position, finds application in creating micelles, liposomes, and various artificial membranes, notably in lipid-based drug delivery systems.
